Who or what is a "bluenose"?

[Vimto]

I have been reading in the sports pages this morning (June 17th 2011) about the likelihood of Alex McLeish becoming the Aston Villa manager. In the article, reference is made to him being a "bluenose" but no explanation or definition is forthcoming. It appears in Jim White's column in the Daily Telegraph. Could anyone please explain the meaning.
On a slightly different slant, is it just me or has the sports section of the Telegraph become a shadow of its former self? Its coverage of some sports has become very poor, even some cricket, including international test matches, are not reported on. Can anyone suggest an alternative newspaper that has a wide comprehensive cover of all sports and is not 80% soccer and which preferably, does without an astrology page!?
